I don't know why anyone would load mags by hand when UpLulas exist! I recently introduced several people in their 60s, who have arthritis, to UpLulas. They saw me loading mags while shooting and were very interested. They borrowed mine, and were amazed they could load mags without hurting their thumbs. They bought one at the range before leaving. I have carpal tunnel, so I've used an UpLula since day one of getting my first pistol in 2013.
